BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to siding for a building structure, and more specifically to siding attachment and alignment devices and systems for a building structure.

2. Description of the Background Art

Many types of buildings include some form of siding. Siding is generally used as an exterior surface to keep out moisture and prevent decay of structural members, protect the building, and also to provide an attractive or durable appearance to the building structure.

In the prior art the siding is generally supplied as elongated panels that are successively applied to exterior walls starting from the bottom of the building structure and moving upward to the top of the building. The panels are generally nailed onto studs of the building, with one nail usually being used per stud.

However, there are several problems in the siding application according to the prior art. First, the siding must be applied in a manner that is substantially level. This is done to ensure that the siding is installed evenly. It is also important from an appearance aspect. Ensuring level and parallel installation is difficult because of the freehand nature of nailing the panels to the studs. In addition, the prior art siding process is relatively slow and cumbersome, and some carpentry expertise is needed.

Therefore, a need remains in the art for improvements in siding attachment devices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 is a fragmentary perspective view showing a siding attachment strip 100 according to one embodiment of the invention. The portion of the siding attachment strip 100 shown in FIG. 1 includes an elongate body 101, one or more mounting holes 108 formed in the body, a siding top edge clip 112 disposed on the body, a siding fold clip 140 disposed on the body in spaced relation to the top edge clip, and one or more lateral scoring marks 152. Also shown is an optional slot 117 formed in the body between the top edge clip and the siding fold clip. The strip 100 preferably includes a plurality of siding top edge clips 112 and a plurality of siding fold clips 140 disposed in a regular pattern on the body to accommodate one or more standard siding panels thereon. In one embodiment, the engaging portions of the two clips may be about three-quarter inch to about one and a half inches apart, and repeat every 8, 9, or 10 inches along the siding attachment strip 100, for example. Other spacings may be used, according to the type and size of siding panel desired to be attached to a building structure.

FIG. 2 shows various cross-sectional shapes of the body 101 of the siding attachment strip 100. The siding attachment strip 100 may include hems, flanges, and/or ribs in order to provide rigidity and strength. The body of the siding strip 100 is preferably U-shaped in cross-section including a front face 105 and two side portions 106, as shown in FIG. 1.

The siding attachment strip 100 is preferably made of a sheet material such as aluminum or steel sheet metal, for example, but also may be made of vinyl, fiberglass, etc. In one embodiment, the siding attachment strip 100 is formed of a 22 gauge sheet metal. In addition, the siding attachment strip 100 may include a weather-protecting coating, such as a galvanized sheet metal, for example. The siding attachment strip 100 may further include one or more lateral scoring marks 152 (optional) that may be used by an installer to snap or break off the siding attachment strip 100 at predetermined locations.

Each siding top edge clip 112 is configured to engage a top edge region of a siding panel (see FIG. 5). The siding top edge clip 112 may be punched out of the body 101 of the siding attachment strip 100 and therefore formed of the material of the body 101 such that the strip can be formed as an integral one-piece unit. Alternatively, the siding top edge clip 112 may snap onto the body 101, or the siding top edge clip 112 may be partially punched out, and a non-punched connecting portion may retain the siding top edge clip 112 to the elongate body of the siding attachment strip 100.

The illustrated siding top edge clip 112 includes a generally flat planar member or flap with a plurality of prongs 114 extending therefrom. Each prong 114 has a length and preferably includes a substantially right-angled bend in a middle region of the prong 114, as shown. The prongs 114 of the top edge clip 112 are preferably formed by cutting slots into one edge of the flap and bending the prongs out of the plane of the flap.

FIG. 3 is an end view of a siding top edge clip 112. The prongs 114 may include tapered portions 115 that aid in passing the prongs through a prong slot 117.

In the embodiment shown in FIG. 1, the siding top edge clip 112 is formed of a bendable material and may be deformed with respect to the body of the siding attachment strip 100 (i.e., the siding top edge clip 112 may be deformed or pressed toward the siding attachment strip 100 when engaging a siding panel). Alternatively, if the siding attachment strip 100 is formed of a resilient material, the siding top edge clip 112 may return to a normal position with the prongs 114 received in and extending through the prong slot 117. Therefore, during installation of a siding panel, the resilient siding top edge clip 112 may be pulled upward and outward, momentarily displacing the siding top edge clip 112 and allowing a siding panel to be slipped underneath.

In an alternate embodiment, the siding top edge clip 112 may be fastened to the siding attachment strip 100 by one or more spot-welds, by adhesive, or by a fastener such as a nail, screw, rivet, or snap-in fastener attachment that engages a hole (not shown) in the siding attachment strip 100. In one embodiment, the top edge clip 112 may rotate on the siding attachment strip 100.

FIG. 4 shows an alternate embodiment wherein the body 101 of the siding attachment strip 100 includes one or more top edge clip slots 134. The one or more top edge clip slots 134 may be formed in the side portions 106, as shown, or may be formed in the front face 105. The siding top edge clip 112 may include one or more corresponding Z-bend projections (not shown) that pass through one or more top edge clip slots 134 in the siding attachment strip 100.

Referring again to FIG. 1, the siding fold clip 140 is formed to achieve a rounded and substantially right-angled bend, and engages a correspondingly shaped siding fold 506 in a siding panel 502 (see also FIG. 5, discussed below). The siding fold clip 140 includes a curved lip edge 145 that curves away from the body 101 of the siding attachment strip 100 and eases entry of the siding fold clip 140 into a siding fold 506 of a siding panel. Like the siding top edge clip 112, the siding fold clip 140 may be also punched out of and formed of the material of the siding attachment strip 100. The siding fold clip 140 may be partially punched out, and a non-punched connecting portion may retain the siding fold clip 140 to the elongate body of the siding attachment strip 100.

The plurality of mounting holes 108 pass through the siding attachment strip 100 and may be used to mount the siding attachment strip 100 to a building structure (not shown). The plurality of mounting holes 108 may receive a nail, screw, rivet, staple, bolt, or other fastener that may be used to attach the siding attachment strip 100 to the building structure. The plurality of mounting holes 108 may be countersunk or otherwise recessed, and may even be threaded for receiving any manner of threaded fastener. Alternately, fasteners can be formed as part of the strip.

In use, a plurality of siding attachment strips 100 may be mounted to a plurality of studs, to an underlying sheeting, or to other support members of the building structure. The siding attachment strips 100 are preferably mounted in a substantially vertical orientation, but can also be oriented horizontally. When the plurality of siding attachment strips 100 are mounted so as to be substantially parallel and level, a plurality of siding panels may then be installed without concern for leveling and aligning each individual siding panel.

FIG. 5 shows the siding attachment strip 100 in use. Attachment strip 100 is preferably placed against the building structure with the side portions 106 facing toward the structure so that the front face 105 is spaced away from the building structure so as to define a space there between for receiving the prongs 114 of the siding top edge clips 112. A siding panel 502 is placed against the siding attachment strip 100. The siding fold clip 140 snaps into and engages the siding fold 506 of the siding panel 502. The siding fold clip 140 holds the siding panel 502 from moving vertically or horizontally with respect to the siding attachment strip 100 (i.e., it substantially prevents the siding panel 502 from moving toward or away from the siding attachment strip 100). The siding fold clip 140 does not, however, restrain the siding panel 502 from moving in a lengthwise fashion, as the siding top edge clip 112 performs this function.

As a second part of installing the siding panel 502, the siding top edge clip 112 may be bent down with respect to the siding attachment strip 100. As a result, one or more of the prongs 114 will pass through one or more nailing slots 508 in the siding panel 502 and will preferably protrude through the underlying prong slot 117 into the space defined between the front face and the building structure. Preferably, a single prong 114 is forced through the nailing slot 508 at approximately the center of the nailing slot 508. By only forcing one prong 114 through the center of the nailing slot 508, there is sufficient remaining clearance in the nailing slot 508 for the siding panel 502 to contract and expand. However, more than one prong can be forced through a slot (see FIG. 6 below and the accompanying discussion).

As is typical in siding installation, a series of siding panels 502 are assembled starting from the bottom of the building structure. Therefore, another pair of clips 112 and 140 may exist above the pair shown, and a bottom edge of a next siding panel will fit under and engage the siding fold 506, as is commonly done in siding installation (see FIG. 9).

FIG. 6 shows how the prongs 114 of the siding top edge clips 112 advantageously pass through nailing slots 508 of the siding panel 502. Clip A is a first siding top edge clip 112 that through coincidence happens to be centered in a nailing slot 508. In contrast, clip B does not fall completely within a nailing slot 508. This is not a problem, however, as at least one prong 114 of clip B still falls within a nailing slot 508 and furthermore falls within a center region of the nailing slot 508.

FIG. 7 is a perspective view of an insulation sheet 700 according to one embodiment of the invention. The insulation sheet 700 has a thickness, an outward side, and a wall side (not shown). The insulation sheet 700 may be made of any suitable home insulating material including, e.g., foam, STYROFOAM, fiber board, particle board, gypsum board, etc. The insulation sheet 700 includes a plurality of horizontally spaced, substantially vertical channels 704 and may optionally include a plurality of substantially horizontal contours 707 formed between the channels. The optional contours 707 are preferably shaped to match the contours of a standard siding panel 502 (see FIG. 9).

The plurality of vertical channels 704 are preferably configured to receive the siding attachment strips 100 according to the invention. The vertical channels 704 include half-width channels 704 a at the edges, where two insulation sheets 700 may mate. The plurality of vertical channels 704 are preferably rectangular in shape but may be other shapes as desired. The vertical channels 704 are spaced at industry standard stud spacing dimensions such as, for example, 12 inches on center, 16 inches on center, 18 inches on center, 24 inches on center, etc. The channels 704 allow the siding attachment strips 100 to be flush with the siding face. Furthermore, the channels 704 may allow the siding attachment strips 100 to be recessed into the insulation sheet 700 and not interfere with or displace installed siding panels 502. In addition, the side portions 106 of a siding attachment strip 100 may be forced into the back surface of the vertical channels 704, at least partially embedding the siding attachment strip 100 into the insulation sheet 700.

FIG. 8 is a front view of an insulation sheet 800 according to another embodiment of the invention. The insulation sheet 800 includes a plurality of tabs 804 on a first edge of the insulation sheet 800 and a plurality of slots 808 on an opposite second edge. The two parts may interlock when two insulation sheets 800 are brought into abutment.

In an additional feature, the insulation sheet 800 may include a plurality of lines 823 that are formed on the siding face of the insulation sheet 800. The lines 823 may be printed, embossed, or impressed onto the insulation sheet 800. The lines 823 may be horizontally or vertically arranged, or both. The lines 823 may be used by an installer to visually align the insulation sheet 800 during installation. Furthermore, the installer may use the lines to visually align siding attachment strips 100 and siding panels 502, which may be installed over the insulation sheet 800.

It should be understood that an insulation sheet 700 or 800 according to the invention may incorporate various combinations of channels 704, contours 707, tabs 804 and slots 808, and lines 823.

In another additional feature, the insulation sheet 700 or 800 may be a fan-fold type of sheet that can be unfolded before installation into an insulation sheet of multiple panels and of a larger area dimension.

FIG. 9 is a section or side view of the insulation sheet 700, showing how the horizontal contours 707 substantially match a contour of a standard siding panel 502. When a siding panel 502 is installed onto the insulation sheet 700, there is substantially no space between the inner surface of the siding panel 502 and the insulation sheet 700 (the channels 704 are not shown in this figure for the purpose of clarity).

It can be appreciated from this figure that the contoured insulation sheet 700 according to the invention provides several benefits. It eliminates a hollow space between the inner surface of the siding and the insulation, therefore increasing an insulation rating of an installed insulation/siding combination. The contoured insulation sheet 700 prevents the siding from rattling and vibrating due to wind, or at least reduces the likelihood and level of siding movement. The contoured insulation sheet 700 also eliminates open space in which insects, leaves, or other dirt may accumulate.

FIG. 10 is a perspective view of a siding starter strip 1000 according to one embodiment of the invention. The starter strip includes a flange 1007, a siding fold 1006, a back wall 1009, and an insulation sheet channel 1014. The siding starter strip 1000 is a first component installed onto two or more siding attachment strips 100 during a siding installation process. The siding starter strip 1000 therefore is a bottom-most component, and preferably rests on or contacts a foundation or sill of the building structure.

When installed, the starter strip 1000 engages and locks onto the bottom-most pair of clips at the bottom of the siding attachment strips 100 (i.e., a siding top edge clip 112 and a siding fold clip 140). The flange 1007 includes a plurality of nailing slots 1008 that receive the siding top edge clip 112. In addition, the siding fold 1006 receives the siding fold clip 140 of the siding attachment strip 100. Furthermore, the insulation sheet channel 1014 receives a bottom edge of an insulation sheet 700 (or any type of insulation sheet).

FIG. 11 is a perspective view of a siding starter strip 1100 according to another embodiment of the invention. As before, the siding starter strip 1100 is a first component installed onto two or more siding attachment strips 100 during a siding installation process. In this embodiment, in addition to the flange 1107 and nailing slot 1108, the siding fold 1106, and the back wall 1109, the siding starter strip 1100 includes a foundation cap 1117 and an angled lip 1122 on the foundation cap 1117.

As in the first embodiment, the siding fold clip 140 engages the siding fold 1106 and an insulation sheet fits into the insulation sheet channel 1114. The foundation cap 1117 may cover a wooden sill at the bottom of the first row of vinyl siding. The angled lip 1122 ensures that the foundation cap 1117 contacts the foundation or sill. The foundation cap 1117 and the angled lip 1122 have the ability to flex to accommodate different distances between the siding starter strip 1100 and the foundation.

FIG. 12 is a section view of an upper wall, an eve, and a roof of a building structure, including a siding/soffit corner piece 1240 according to one embodiment of the invention and a facia board cover 1205 according to another embodiment of the invention. The siding/soffit corner piece 1240 and the facia board cover 1205 are designed to be used for a roof overhang, where the building structure includes at least a wall 1201, an insulation sheet 1202, a facia board 1292, and a roof 1291.

The facia board cover 1205 extends over the facia board 1292 and may cover it with a finished external surface, such as a vinyl surface that may match a siding used on the building structure. The facia board cover 1205 includes a soffit channel 1208 that receives and holds one end of a soffit panel 1298. The facia board cover 1205 further includes a plurality of soffit clips 1280 that are spaced along the length of the facia board cover 1205 and that retain a plurality of soffit panels 1298. The soffit clips 1280 are identical to the soffit clips 1280 of the siding/soffit corner piece 1240 (see FIG. 14 and the accompanying discussion). The facia board cover 1205 further includes a roof flashing portion 1212 that extends upward over a portion of the roof 1291. Roofing may be installed over the roof flashing portion 1212, or the roof flashing portion 1212 may alternatively be inserted underneath an existing roofing material. The roof flashing portion 1212 further includes a fold 1209 that allows the roof flashing portion 1212 to be bent and adjusted as desired to fit the slope of the roof 1291. The facia board cover 1205 may be attached to the facia board 1292 by fasteners (not shown) that pass through one or more mounting holes 1216.

FIG. 13 shows detail of the siding/soffit corner piece 1240 in a profile view. The siding/soffit corner piece 1240 includes a top portion 1244, a soffit panel channel 1248, an insulation sheet channel 1252, a soffit panel support portion 1259, a siding channel 1263, and a siding retaining lip 1265. The siding/soffit corner piece 1240 may further include one or more mounting holes 1246.

FIG. 14 is a fragmentary side view of the siding/soffit corner piece 1240, illustrating the plurality of soffit clips 1280. The soffit clips 1280 extend from the top surface 1244 and are spaced to correspond to a size of a standard soffit panel 1298 (See FIG. 12). The soffit clips 1280 may therefore engage a soffit panel fold similar to the siding fold 506 of a siding panel 502.

In use, the siding/soffit corner piece 1240 may be mounted to the wall 1201 (see FIG. 12) using the one or more mounting holes 1246 and a suitable fastener, such as nails, screws, etc. An end of the soffit panel 1298 may be fitted into the soffit panel channel 1248 (see FIG. 12). A top end of an insulation sheet 700 or 800 may be fitted into the insulation sheet channel 1252. A siding panel 502 may be fitted into the siding channel 1263, wherein a top edge of the siding panel 502 is forced under and retained by the siding retaining lip 1265. In this manner, the top-most panel of a plurality of siding panels 502 is securely retained. This is beneficially achieved without need for nailing in a corner between the junction of the siding and the soffit panel 1298. Furthermore, the siding/soffit corner piece 1240 according to the invention presents a finished exterior appearance, and with no visible fastener.

A corresponding method of providing a siding mounting system includes providing a siding attachment strip 100 adapted to be attached to a building structure. The method further includes forming a plurality of siding top edge clips 112 on the siding attachment strip 100, with a siding top edge clip 112 being spaced to engage one or more nailing slots 508 along a top edge of a siding panel 502. The method further includes forming one or more mounting holes 108 on the siding attachment strip 100. The one or more mounting holes 108 may optionally be recessed into the siding attachment strip 100. The method further includes forming a plurality of siding fold clips 140 on the siding attachment strip 100, with a siding fold clip 140 being spaced below a corresponding siding top edge clip 112 and spaced to engage a siding panel fold 502. The plurality of top edge clips 112 and the plurality of siding fold clips 140 may be stamped or punched out of the siding attachment strip 100. In addition, the method may include forming a siding attachment strip 100 of a sheet material formed into a U-shaped channel, and it optionally may include a hem on the side portions 106 thereof.

FIGS. 15A, 15B-17 show another preferred embodiment of a siding attachment strip 1501 according to the invention. In this embodiment, each siding top edge clip 1503 is provided with five fingers 1503 a. The provision of five fingers enables the siding top edge clip to compensate for all variations in siding panel horizontal nail slot widths. Additionally, each finger has rounded edges 1503 b, which allows easier clip-on attachment to siding panels. The center screw hole 1509 is provided with a chamfer 1510 so that the attachment screw for attaching the siding strip 1501 to a wall stud may be recessed into the strip, thereby avoiding the possibility of catching on a siding panel. The top edge clip 1503 includes a half-round gusset 1503 d (see also FIG. 17), which provides extra strength against breakage of the top edge clip when it is bent downward to engage the nail slot of a siding panel. Siding fold clip 1505 is also provided with gussets 1601 (see also FIG. 16), which provide added strength to the bending resistance of the siding fold clip.

Additional features include a PVC coating 1510 applied to the strips 1501, which acts as a vinyl thermal barrier to reduce condensation that would be caused by contact of the back of the vinyl siding panel with a metal strip. This will eliminate or reduce the accumulation of debris on the siding panels along locations over the attachment strips caused by increased condensation on the siding panels at those locations due to contact with metal. Alternatively, the strip 1501 may be manufactured from fiberglass material, wherein the clips 1503 and 1505 are made of PVC or metal material, and snap onto the fiberglass strip.

FIG. 18 shows an alternate embodiment of a foam insulation sheet 1800, containing additional channels 1802 in addition to the main channels 1801 that receive siding attachment strips. The additional channels 1802 function as ventilation channels that allow moisture under the siding attachment strips to escape through ventilation slots provided a trim adaptor (discussed below) and ventilation slots provided in the starter strip (see FIG. 10).

FIG. 19 shows a trim adaptor 1900 according to another embodiment of the invention, for allowing installation of a top siding panel at the top of a wall. The trim adaptor 1900 includes a number of nailing slots 1904 and ventilation slots 1902, which also can be used as nailing or screw slots for securing the trim adaptor to a soffit. A channel 1906 accepts a utility trim piece, which in turn attaches the top siding panel by a snap-on attachment. As shown in FIGS. 25A-25C, the trim adaptor 1900 is mounted over the top of a siding attachment strip 1501. The siding attachment strip is provided with a cutout 2501 that receives a projecting end 2502 of the trim adaptor to secure the trim adaptor to the top of the siding attachment strip. Additionally, the trim adaptor 1900 may be used to install a J-channel piece around windows and doors. It also can be used to install vinyl siding corner posts, and building out the corner posts, top panel and J-channel around windows and doors, and up gables and peaks. The upwardly extending leg of the channel 1906 also is used as an additional locking point for the top siding panel. By simply reversing the crimp in the siding panel, the crimp may be inserted into the channel formed by the extending leg, to provide a second locking point in addition to the conventional locking point with the utility trim piece.

FIGS. 20-23 illustrate a combination utility trim/J-channel adaptor and soffit return channel adaptor 2001 according to another embodiment of the invention. The combination adaptor is used for installing utility trim pieces 2100 similar to the adaptor 1900 (see FIGS. 21 and 22), and in addition has a soffit return channel 2003 that receives soffit overhang pieces 2300 (see FIG. 23). A number of stops 2005 are provided in the channel 1906 to accommodate different widths of utility trim pieces and J-channel pieces.

FIG. 24 shows an embodiment of the invention that provides ventilation between a roof overhang and a soffit panel. A spacer channel 2400 is formed between a vinyl soffit panel 2404 and a roof overhang 2406, through the use of foam pieces 2402 that are mounted to the roof overhang with screws or nails, in conjunction with a wood block 2408 attached to the exterior wall. The wood blocks 2408 also can be used to attach siding attachment strips to open-end tail rafters, without the need to install furring strips.

FIGS. 26A and 26B illustrate another preferred embodiment of a starter strip 2601 having score lines 2602 that allow the length of the bottom piece of the starter strip to be adjusted for different spacings between the foundation wall of a building and the main level exterior wall. Additionally a flex area 2604 is provided that allows the end of the starter strip to flex downward against the foundation wall.

FIG. 27 shows another preferred embodiment of a siding clip according to the present invention. In this embodiment, a clip 2702 is provided in place of the clip 112 (see FIG. 1). Clip 2702 snaps into the finger slot 117, and has a finger 2704 that engages a nail slot 508 of a siding panel 502 from the rear of the siding panel, and comes up through the nailing slot. The snap-on clip 2702 will move side-to-side with the siding panel, to thereby enable the siding panels to have lateral movement for proper alignment.

FIG. 28 shows an embodiment of a fascia board adaptor 2800, which allows a fascia board piece 2802 to be snapped-on to a roof overhang 2804, without the need for any fasteners.

The devices and method described above are particularly applicable to wood frame dwelling structures but may be used for any building structure using vinyl, steel, wood, fiber cement, fiberglass, or any other type of siding. The invention differs from the prior art in that prior art siding installation is typically done by a single nail through a slot in the top of the siding, with one nail being used per stud. Therefore, the installer must have some skill in alignment and nailing and must pay attention to maintaining a proper alignment for each siding panel that is installed. In addition, in the prior art insulation has been provided in flat sheets that leaves hollow regions under the siding. The prior art insulation sheet results in a lower level of insulation, a place for dirt and insects to accumulate, and may allow more room for the siding to rattle or vibrate against the building structure.

The invention provides several benefits. The siding attachment strip 100 provides snap-on installation of siding panels 502. The siding attachment strips 100 are easier to install for non-experienced siding installers. The siding attachment strips 100 according to the invention advantageously may accommodate standard siding panels. In addition, when the insulation sheet 700 or 800 and the siding attachment strip 100 are used in conjunction, the installer does not need to find the stud below the insulation sheet 700 in order to drive a nail (in the prior art, the installer might miss the stud and therefore damage the insulation sheet). The siding attachment strips 100 allow lateral expansion and contraction of the siding, wherein the prongs 114 are engaged in the nailing slots 508 and may allow the siding panel 502 to expand and contract due to temperature. Moreover, the siding attachment strips 100 ensure alignment of siding panels 502. When the siding attachment strips 100 are installed and aligned, the installation of the siding panels 502 may be done without concern for alignment and leveling, as is necessary in siding installation in the prior art. In addition, no special tools are needed for siding installation. The siding panels quickly and easily snap into the pairs of clips. The siding attachment strip 100 according to the invention virtually ends improper nailing of the siding by guiding the siding installer and ensuring that the proper spacing is maintained between siding panels 502.
